One of these tactics is shorting.
Normal sharemarket investing relies on you putting money into businesses that you think will do well, and then getting a share of the profits if they do.
But if you short, the idea is that you're betting against businesses that you think will do badly, and if they do indeed have a bad run, you'll get a profit that way.
Retail investors - that's the little guy like you and me - have been dabbling in shorting recently.
Investment platform Stake let me have a peek at the trends for their investors, and the top results were very interesting.
The top favourite stock is Tesla, which has been a fan favourite for a while.
But the next two speak volumes.
One is the SQQQ, an ETF fund which shorts the Nasdaq, essentially betting against digital and technology companies.
Following that is the TQQQ, an ETF fund which invests into the Nasdaq, essentially a vote of confidence into digital and technology companies.
Clearly, investors are divided on what they think the future holds.
So, let's dive into this fascinating issue, and see whether you should give shorting a go yourself, and how it all works.
