#我的七夕交易分享 8.17 Monday morning's latest Bitcoin and Ethereum outlook and analysis
Looking at the four-hour chart, after Bitcoin surged to the previous high of 65474, bullish momentum gradually weakened, forming a clear pattern of lower highs. The price has remained under pressure and pulled back, currently trading around 62892. The four-hour moving averages are turning downward and suppressing the market, while the rebound momentum is very limited. Each modest rally has been accompanied by selling pressure, making the rebound a weak recovery, with no high-volume reversal signal. Although the MACD indicator has formed a slight golden cross, momentum is not strong, favoring a rebound correction during the decline rather than the start of a new upward trend.
In terms of trading volume, volume has continued to shrink during the rebound, indicating insufficient willingness from bulls to follow through and heavier pressure from trapped positions above. Overall, bears have the upper hand, and the market is more likely to continue its downward trend. The resistance zone above is 63500‑64200. As long as the price cannot effectively hold above this range, the rebound will struggle to go far. First, watch the support around the previous low of 62270. If this support is broken on heavy volume, further downside will open up, with the next target at the 61100 level.
Morning trading approach
Bitcoin can be shorted in the 63200-63500 range, with a target of 62300
Ethereum can be shorted around 1880, with a target of 1850

#股票交易分享挑战 SanDisk—A Group of Gamblers Standing Beneath the Fireworks on an Island
SanDisk’s August 5 earnings call and August 13 Investor Day disclosed nearly identical company fundamentals and financial information to the market, yet the market reactions were diametrically opposed: the stock plunged 13% after hours on earnings day, then surged 13% after Investor Day. This shows that in a rapidly changing market environment, similar news can indeed produce completely opposite moves when “old goods are put in new clothes.” We took a close look at what additions this “new outfit” made and what structural changes it introduced.
By contrast, the Philadelphia Semiconductor Index has spent the past two days stuck at resistance with declining volume and stagnant gains, seemingly waiting for Nvidia’s earnings report on August 26 and the monthly OPEX expiration on August 21 to determine its direction.
When a stock can surge 22% in two days on the highest trading volume among all U.S. stocks, while the sector ETF it belongs to is drifting lower on declining volume, it means the price-discovery function has left funds sensitive to fundamentals and shifted into the hands of funds sensitive to volatility. The former buy companies; the latter buy price swings. The former wait for earnings, guidance, and the fulfillment of multiyear contracts; the latter wait only for the next person to take the asset off their hands at a higher price.
July as a whole marked the peak of the deleveraging in semiconductor memory stocks: leveraged long positions were liquidated, and forced-liquidation positions were dumped onto the market, creating a stampede. Once the bubble had been fully deflated, however, a short-squeeze-style oversold rebound emerged, leaving shorts trembling. The market seems to be staging a double blowup of longs and shorts. Once short covering reaches its critical point and the short squeeze exhausts its fuel, it will be a difficult moment to control.
The fireworks were brightest on August 13–14; their fuel will run out on August 21, the OPEX date; and they will be completely extinguished after NVDA’s earnings report on August 26. These three time gates will determine whether “the gamblers beneath the island’s fireworks” continue adding to their bets or rush for the exit.
If Philadelphia Semiconductor shorts still do not step up their covering after August 21, and Nvidia’s earnings report is bearish as expected, SanDisk’s short squeeze will become “the last fireworks on the island”—brilliant, brief, and with no one to carry the torch. SOXX shorts will wait for the day they get the “echo segment breakdown to the downside” they want.$SNDK
