Grain Rain Season ETF-0713 Recap | Follow the Trend to Split Trades and Avoid Quant “Harvesting”

Guyu Season ETF-0713 Recap｜Follow the Trend to Split Orders, Avoid Algorithmic “Harvesting” of Volume

I. Guyu Seven-Character Ode · Trading Insights

Spring rain nourishes seedlings; trading to cultivate the mind, not to be arrogant.
Quantitative selling can trigger heavy oscillations; with light positions, swing-trade—stay far from wild noise.
When price spikes, trim and take profit at appropriate points; when it pulls back, low-buy—don’t chase highs.
Diversify across three sectors to hold the bottom line; compounding slowly, the road ahead is long.

II. Recap Main Text

Today’s broader market moved down one-directionally, closing down 2.06%, as quantitative funds concentrated to smash the leading sector tracks. Space, robotics, and chips all suffered sharp declines, and panic sentiment spread across the market.
Looking at market patterns: hot themes swing violently, and chasing at the short-term highs is prone to being harvested by quant trading. Only pharmaceutical innovation drugs managed to show relatively resilient performance, and institutional “risk-avoidance” demand became prominent.
The core logic of the Guyu trading system: don’t heavily weight a single sector; don’t gamble on short-term consecutive-limit-up行情. Instead, mainly run rolling swing trades using an ETF core allocation. In the face of extreme sell-offs, prioritize controlling drawdowns, split the positions to rotate out of weakness and retain strength, don’t rely on one-off blowout profits—build returns through steady and robust compounding.
Current market conditions: the index is in an oversold range, but the short-term selling pressure on the main sector tracks hasn’t been fully released. Don’t rush to go all-in on a bottom; follow the Guyu position “layering” approach.

III. Disassemble Holdings One by One (Corresponding to All ETFs in the Chart)

1. 513120 Hong Kong-listed Innovative Drugs ETF (T+0)
   Down on the day: -1.86%. In the selected universe, it was the single best performer with the smallest decline. In the healthcare space, AI-driven drug R&D has helped improve fundamentals, and the interim report performance has support. This belongs to a long-term institutional layout sector and is the first choice for risk-avoidance. A choppy market is suitable for small-position, repeated T+0 rolling trades; a small short-term pullback doesn’t need panic. As a core holding for defense, it’s the bottom-line protector.

2. 159206 Satellite ETF Yongying
   Plunged 9.92% in a single day. Over the weekend, space-related positives landed and were realized; once the good news was “fully priced,” a quantitative coordinated sell-off hit hard, and short-term sentiment completely weakened. At this moment, it’s clearly a weak product. Follow the “stay with strength, cut weakness” mindset: on the next day’s bounce, trim or fully exit in portions; don’t blindly bottom-fish and bet on a rebound.

3. 159613 Information Security ETF
   Down: -3.51%. A subdivision of the digital economy. Its trend followed the technology main line and weakened in tandem, without any independent ability to resist declines. There’s no clear stabilization signal yet. Keep the bottom-line holding portion and wait for the 20-day line to stabilize before adding.

4. 561980 Semiconductor Equipment ETF
   Down: -3.77%. A chip-industry chain sub-segment. The industry’s medium-to-long-term logic remains, but in the short term market sentiment is weak. Don’t add new positions; observe and wait for a stabilization signal.

5. 511880 Yinvestra Daily ETF (T+0) Cash Reserve Pool
   Slightly down: -0.01%. A cash management tool with no volatility risk. In the phase of panic and big drops, all idle funds are moved into this daily “risk-avoidance” allocation, balancing liquidity and small returns—an “escape harbor” for funds on big down days.

6. 588200 STAR Market Chip ETF
   Down: -5.10%. A broad core chip exposure. Its volatility is higher than equipment sub-sectors. High-frequency quantitative trading is frequent, so it’s only suitable for short-term, small-position swings; it can’t be heavily weighted for long-term holding for now.

IV. Guyu Position-Splitting Practice “Mindset” (For Retail Only)

1. The “Sector Diversification” Iron Law
   Hold at most 3 sector tracks. Don’t bet all funds on a single technology track. The total number of single-stock ETFs should be kept within 3–5, to avoid over-diversifying and becoming hard to manage.

2. Position Tiering Standards
   Newcomers with less than 3 years in the market: the normal total position should be within 1/10 of capital, with a maximum not exceeding 2/10; small funds should repeatedly practice swing trades. For old retail traders with more than 3 years: in a choppy market, total positions should not exceed 5/10. No single ETF position should exceed 2/10 of total funds.

3. Hard Stop-Loss Rules
   If an individual asset’s unrealized loss reaches 5%, reduce position / fully exit without conditions. If it effectively breaks below the 20-day line, proactively cut down—never “stubbornly hold and get deeply trapped.”

4. Divide Funds into Three Parts
   One part: core bottom-line holding for long-term ownership of quality sectors.
   Two parts: funds for trimming high and taking profit.
   Last part: reserve cash to wait for a sharp drop, then low-buy.
   This perfectly handles the quant back-and-forth “smash-into-oscillation” style market.

5. Strength/Weakness Switching Principle
   If a sector track weakens and sell-off continues on increasing volume, execute “stay with strength, cut weakness,” and move funds into defensive main lines like innovative drugs. Avoid popular themes that quants focus on harvesting.

V. Operation Plan for Tomorrow

1. Weak holding 159206: On the next day, if there’s a small rebound, reduce or fully clear in batches immediately; compress the total allocation to the weak track—don’t have unrealistic hopes.
2. Technology ETFs (588200, 561980, 159613): Mainly stay in wait-and-see mode. If they haven’t firmly stood above the 20-day line, don’t add new buying—only keep and roll the existing light core.
3. 513120 Innovative Drugs ETF: Hold as the core defensive bottom-line. Use the T+0 mechanism—trim on intraday spikes and lightly buy on sharp pullbacks—to hedge the risk of market downside through intraday swings.
4. Idle funds: Fully allocate to 511880 Yinvestra Daily as a defensive hedge, and wait for market sentiment to stabilize before reallocating to enter.
5. Overall position control: Keep total positions within 3/10 tomorrow. If the broader market keeps weakening, further reduce to 1–2/10. Prioritize protecting principal.

VI. Conversation Scripts at the End

My初心 is simple: I just want to help fellow retail traders take fewer detours. I’m not betting on short-term speculation to get rich quickly; I rely on the Guyu system for steady compounding.
Each month, I’ll only screen 3–5 assets that I’ve validated through personal real-trade practice. Only after you buy and confirm the logic will I share it. Quality over quantity—only do the best opportunities. I aim to make the whole account finish each month with profits.
If you currently hold any ETFs or have questions about your holdings, you can leave them in the comments to ask. Once Guyu sees them, I’ll reply one by one as soon as possible.

VII. Complete Risk Warning

1. All recap ideas, position planning, and operation plans in this article are for personal real-trade experience sharing only. They are purely for educational purposes and do not constitute investment advice or force anyone to follow the same actions.
2. The A-share market is highly volatile. Quantitative funds can intensify intraday up-and-down moves. ETFs traded on-exchange carry price fluctuation risk. T+0 trading makes frequent operations more likely to expand losses. Participate based on your own risk tolerance.
3. Rigorously control trading principles for idle funds: don’t borrow or add leverage to trade stocks. Set fixed stop-losses to prevent large losses from a single drawdown wiping out principal.
4. Sector fundamentals, macro news, and overseas market conditions can all change sector performance. The market always has a risk of downside beyond expectations. All actions must adapt flexibly—don’t mechanically copy the recap plan.
