In the past, as long as you could buy and hold in the bull market, it would be fine. In this round of bull market, the funds switch faster. For the cottage, you must know how to sell and be able to lock in the profits. Selling fast will always make money. Don't be too patterned and lose all the profits in the bear market.
After this wave of reshuffle is completed, the cottage market will rise again, but it will no longer be the overall rise of the past bull market. Good targets may be able to run dozens of times, while bad targets are very likely to not outperform the market. It is important to choose a good target. If you choose the wrong one, it is more important to dare to change the position. Don't be dragged down by the silent cost.
