Well Nasdaq started the year at 19280, at 20410, so not really "that much" of an increase, it was already at 20k, but had a huge crash (thanks to trump and tariff war stuff in between) to 15k and now it's 20k. So if you think 19k to 20k is big, look at how we moved from 20k to 15k to 20k in like a month or two, market is volatile, so this small increase is nothing. SP500 was also about 5900 and became 6200, once again very small increase.
Market is healthy in the sense that if Trump doesn't touch it and doesn't do anything bad, then we are not going to end up with any trouble at all. But we just need to make sure that we are seeing how it could move differently. If we can do it, and can stop Trump from making stupid moves, then yeah we can see it grow more.
