Have you noticed? The recent market has been a bit crazy.

Stocks, gold, silver, copper prices, money market funds... almost all mainstream asset classes are hitting new highs simultaneously. It seems like opportunities are everywhere, and investors are shouting one after another about the "second half of the bull market," with enthusiasm at an all-time high.

But here’s the problem: when the global markets continue to strengthen and everyone is celebrating, it’s precisely the time to stay alert.

History has given us many lessons. Take Newton, for example—this scientific giant also experienced setbacks during market bubbles. He witnessed the South Sea Bubble of 1720, when, just like now, various assets soared together, and everyone believed they were the chosen ones. What happened then? On the day the bubble burst, even a genius like him couldn’t escape bankruptcy.

When the market is euphoric, it’s easiest to lose rationality. Multiple assets reaching new highs may seem prosperous, but in reality, they could be signaling that risks have accumulated to a significant level. What to do next is something every trader should carefully consider.
