Most people in a Bull Market would think that the Bull Market won't end, and they won't be affected. People in a Bear Market would think that it's still early, and they will get on board later, causing them to miss the rise and be there for the fall every time, whether it's a bull or bear market. Remember not to chase small rises, not to add to small falls, buy during a big dump, and sell during a big rise. Always be prepared, observe the market trends, and dynamically adjust the proportion of Short Positions. Never go all in, have money to pick up bargains during big dumps, and won't be caught empty-handed during big rises.
