@tn8710 5 years and less is considered short term when it comes to financial goals. If you really want to nit pick the naming of lengths of time, then some people consider 3-10 years "intermediate term". Either way, the majority of financial advisors will all say that money that you plan on using in 5 years or less should not be kept in the stock market.
Good for you for your returns. I don't really care. The past two years have been part of one of the largest and longest bull runs. Just about every index fund has had large returns. That's great for your retirement and other long term accounts. It doesn't justify putting money that is part of a short term goal into the stock market. You have a really high risk tolerance, and it paid off during a bull run. That doesn't mean that it is a good decision for someone else to put their down payment for a house into the stock market.
For OP and anyone else reading this, do not listen to myself or this other user. Do your own research, see what actual financial experts recommend for saving vs investing, and what they consider "short term". Surprise, just about every respected financial advisor and website you can find will consider 5 years or less to be short term, will even specifically mention saving for a down payment as a short term goal, and will recommend keeping those funds in bonds and high yield savings accounts.
