Frankly speaking, should I invest now or next year?

Don't think of market cycles, nobody can predict them

You maybe would like to gather some ideas here:

As what many have said "time in the market rather than timing the market" that being said, if you are looking at lumpsum investments, you'd first have to find opportunities and deduce from there on whether you feel its over or undervalued. No one knows when recession strikes, the main thing is to not put all your eggs in one basket.

It’s very difficult to time the markets, and even when there’s a downturn, the “window of opportunity” doesn’t last long and you won’t know what’s the bottom. Time in market is probably better than timing the market.

You should be flexible. If you feel that the market is slowing or going to be worst, go short. Change it to long once the market is recovering.
