Should I skip my SEP IRA contribution this year and wait for the market to crash further before investing?

Should I skip my SEP IRA contribution this year and wait to see how bad things get?

I'm 41, self-employed, and trying to figure out if I should contribute $40K to my SEP IRA right now or just wait and see how the next few months play out. Would love to hear from people with real experience, not just the standard always-contribute advice.

Here's where I'm at. My SEP IRA is worth about $260K and it's currently all in Franklin Templeton which is pretty heavy on tech and growth stocks. I have enough cash sitting around that the $40K contribution wouldn't hurt my emergency fund at all. I'm self-employed and my income is variable but I'm targeting somewhere around $300-400K this year.

My advisor wants me to make the $40K contribution to bring my total to $300K, then split it evenly across three funds: Franklin Templeton for aggressive growth, Capital Group Growth for more diversified global exposure, and JP Morgan Value as a defensive anchor. Her reasoning is that at 41 I'm young enough to stay growth oriented and that spreading across three different styles gives me some protection.

The problem is I just don't trust the advice right now. She gets paid based on how much I have under management so she's always going to push me to contribute more. That's just her incentive.

More importantly I don't think the market has bottomed yet. With the oil shock, the Strait of Hormuz situation, and everything going on geopolitically, I feel like we're still in the early stages of a bigger downturn. Putting $40K in right now feels like catching a falling knife.

What I'm thinking about doing is filing a tax extension and just waiting until September or October to decide. SEP IRA contributions can be made up to the extended filing deadline so I have time. If markets drop hard over the summer I can contribute at lower prices and still get the tax deduction. If things look really bad I can skip the year entirely and hold onto the cash.

A few things I'm genuinely curious about. Does waiting to contribute make sense or am I just kidding myself about being able to time this? Is the three fund split she's recommending actually solid for someone my age with my concerns about tech? And would you personally trust an AUM advisor to give you unbiased advice in a market like this one?

What would you actually do here?
