Is the Semiconductor Rebound Just the Beginning? 4 Investment Areas Behind AI Computing Power!

South Korea’s KOSPI surged intraday, with Samsung and SK Hynix becoming market focal points. But focusing only on these two stocks could mean missing broader AI investment opportunities.
The AI computing power supply chain is a long track, and capital won’t necessarily revolve around chip giants forever.
I think four areas are worth researching.
First, HBM memory. Demand for high-performance memory in AI computing continues to grow, making technological competition and product mix upgrades worth wat

🚨 $ETH USDT – A BIG MOVE COULD BE BREWING!

I'm watching Ethereum ($ETH) closely because the 15-minute chart is showing an interesting battle between buyers and sellers. After a sharp sell-off from the $2,236 region, ETH recovered from the $2,079 low and is now holding around $2,123.

The market is trying to build a base, but bulls still need to reclaim nearby resistance. I'm watching the $2,110–$2,120 area for a potential bullish continuation. A strong move above $2,135 could open the door to higher targets. 👀

What Is SHAP? How Can We Explain Why a Machine Learning Model Makes a Bullish or Bearish Prediction?

In crypto quantitative trading, machine learning models may predict future price movements based on features such as price momentum, trading volume, volatility, and funding rates. But when a model predicts a bullish or bearish outcome, that does not mean traders know why it made that prediction. SHAP is a method for explaining model predictions by analyzing how different features contribute to an individual prediction.

First, what is SHAP?

SHAP is based on the idea of Shapley values, which a

🚨 $BTC at a make or break level — bounce or breakdown?

Bitcoin is trading around $74,800, holding just above the 200-day moving average ($73,194) after dumping from $87K down to the $73,400 low.

📊 Chart structure:

• Price is well below the 50-day MA ($81,466) — the trend is still bearish

• RSI (14) is at 32.3 — near oversold, sellers are getting exhausted

• MACD is still bearish, but momentum is slowing right into the demand zone

🔑 Key levels:

Resistance: $75,500–$76,200 zone, then $81,200 (50-day MA area)

Support: $73,200–$73,400 demand zone (30-day low), then $70,000

ETH higher-timeframe strategy: →♥

A weekly swing strategy for gradually building a long position may be worth trying at this stage. The timeframe is long, so there is relatively more room for error, while the initial static risk/reward ratio is also decent. Start building a position at Level 1. If a valid reversal occurs, raise the initial stop-loss accordingly. What counts as a valid reversal? For example, after entering at Level 1 (in batches within the 1978–2012 range), if the initial stop-loss (around 1924) has not been triggered and price reaches the first take-profit level (around 2242)

What Is Time-Series Cross-Validation? Why Shouldn’t You Randomly Shuffle the Training and Test Sets for Cryptocurrency Predictions?

In quantitative cryptocurrency trading, machine learning models are often trained on historical data to predict future price movements. But if all the data is randomly shuffled and split into training and test sets, as in ordinary classification tasks, the chronological order may be disrupted, making the model’s evaluation results overly optimistic.

First, what is time-series cross-validation?

It is a method of organizing training and validation chronologically

What Is Backtest Overfitting? Why Might a Strategy With Perfect Historical Performance Fail Completely in Live Trading?

In cryptocurrency trading, some people keep adjusting indicator parameters, take-profit and stop-loss levels, and entry conditions until the strategy achieves the highest returns in backtests. But better historical performance does not necessarily mean a strategy is more reliable. Overfitting historical data may instead make a strategy less able to adapt to future markets.

First, what is backtest overfitting?

Backtest overfitting occurs when a strategy is excessively tailo

US stocks are finally showing some signs of life! 🔥

On one hand, US October CPI is about to be released; on the other, the S&P 500 just posted its biggest single-day gain in nearly 7 months, giving the market plenty to talk about.

Here are three key areas to watch:

📊 **Inflation:** Can CPI continue to cool? If the data comes in below expectations, will rate-cut expectations rise further?

₿ **Crypto market:** Can BTC continue to rebound on macro tailwinds, or will we see another “buy the rumor, sell the news” event?

What Are ROC Curves and AUC? How Can You Tell Whether a Price-Movement Prediction Model Can Truly Distinguish Outcomes?

In crypto quantitative trading, a model’s effectiveness cannot be judged by accuracy alone. Suppose BTC does not make a sharp move upward most of the time. A model that always predicts a decline might achieve seemingly good accuracy, yet fail to identify genuine opportunities to buy. ROC curves and AUC can help us evaluate a model’s ability to distinguish between different outcomes.

First, what is an ROC curve?

An ROC curve compares the true positive rate with the false po

$GT I've been dollar-cost averaging into GT consistently and forgot to post, so here it is now. GT seems to be the only one I DCA'd that hasn't taken a big loss. I bought some when it was at six. Ah, I should've bought more. The other coins I've been DCA'ing have tanked. Guys, if you have spare cash, DCA in.
