Soaring to $905! $SNDK surged overnight, leaving shorts completely stunned

This guy works at a security booth during the day and makes one trade at night—no stress about life.

SanDisk surged to $905 intraday last night, sparked by one key factor: November NAND contract prices jumped 50%, far exceeding market expectations. The third price hike this year has fully ignited the memory sector. Morgan Stanley swiftly rated SNDK “Overweight,” while demand for high-performance flash memory from AI servers continues to soar. Supply is expected to remain tight at least through 2028. This isn’t a rebo

What is model calibration? Why doesn’t a 70% probability of a price increase mean the price will definitely rise?

In cryptocurrency quantitative trading, a machine learning model may predict a 70% probability that BTC will rise in the next period. But this does not mean the price will definitely rise, nor does it mean the model is actually 70% accurate. To understand whether probability predictions are reliable, it is important to understand model calibration (Probability Calibration).

First, what is model calibration?

Model calibration concerns whether predicted probabilities match actual

What Is a Transaction Cost Model? How Can Backtest Results Better Reflect Real Trading?

In cryptocurrency trading, some strategies deliver high returns in historical backtests but perform poorly once real capital is deployed. The problem may not lie in the strategy signals themselves, but in the backtest’s failure to fully account for real trading costs. A transaction cost model incorporates these real-world factors into calculations to evaluate a strategy’s actual performance after costs.

First, what is a transaction cost model?

It estimates the various costs incurred when executing a stra

🚨 Trump Media's $409.7M Q3 Profit Raises an Interesting Question About Crypto!

Trump Media, the company behind Truth Social, has reported $409.7 million in Q3 profit, with gains from its digital asset holdings contributing significantly to the result.

This is an interesting development because it shows how crypto exposure can influence the financial performance of a publicly traded company.

The bigger story isn't just the profit figure. It's how digital assets are becoming increasingly relevant to corporate balance sheets.

Could we see more companies using crypto holdings as part of their

What Is Data Leakage? How Is It Different from Look-Ahead Bias, and How Can You Avoid Misjudging Machine Learning Trading Models?

In crypto quantitative trading, machine learning models may achieve very high accuracy on a test set but perform poorly once deployed in real trading. Sometimes the problem is not that the model is insufficiently complex, but that data leakage occurred during training and evaluation, allowing the model to indirectly access information it should not have known.

First, what is data leakage?

Data leakage occurs when information that should not be available for the c

What Is Survivorship Bias? Why Can Studying Only Coins That Still Exist Today Overestimate a Strategy’s Returns?

In the cryptocurrency market, some traders select currently popular and actively traded coins for historical backtests, then use the results to judge whether a strategy works. But if they ignore projects that have been delisted, lost liquidity over time, or performed very poorly, the backtest results may be systematically biased. This phenomenon is known as survivorship bias.

First, what is survivorship bias?

It refers to focusing only on objects that still exist or have succeede

Today's early-session BTC rebound-short setup has played out in the expected direction.
After rebounding, the price failed to break higher and sustain the move. Overhead resistance held firm, and the price gradually pulled back, in line with the early-session forecast of a rebound facing resistance and turning lower. Although it has yet to fully reach the downside target, the move of the rebound meeting resistance and pulling back has already unfolded, confirming the early-session assessment. The market remains choppy, so risk management should remain a priority. Continue to watch how support

The U.S. CPI report will be released tonight at 10 p.m. The main expectations aren’t too bad—for example, a rise of around 7% in the core index would be positive news. Why? Because the market and U.S. stocks have fallen over the past few days, already pricing in a lot of negative news. Unless this CPI reading, along with inflation, has reached an uncontrollable level, I’m bullish on the cryptocurrency market as a whole.

South Korean stocks rebound sharply: Short-term recovery or the start of a new rally? I favor SK hynix
The KOSPI rebounded sharply today, rising more than 5% at one point intraday and closing up around 4.4% at 5,239 points, ending its losing streak. Samsung Electronics rose around 4.7%, and SK hynix gained around 6.7%, as AI and semiconductor stocks heated up again. The rally followed a rebound in US chip stocks (the Philadelphia Semiconductor Index surged, with AMD and others performing strongly) and represented a recovery from last week's selloff, triggered by concerns about data center regu
