There is no doubt that the Fed will cut rates on Wednesday, we just don't know whether it will be 25 or 50 basis points. Look at data presented in the second tweet below and design an options strategy to profit from this. Pros need not bother. Learners - please don't be shy. Comments are not screened.

Historically speaking, the S&P 500 returns +15% within a year of the 1st rate cut if there is no recession.

If there is a recession, the S&P 500 loses *15% in the first year, on average.

а вероятность рецессии какая предполагается? 1/2?
если 1/2 - то тогда это не особенно отличается от любой другой временной точки, если я правильно помню, annual historical volatility of SPX - обычно 13-18%. соответсвенно задача - придумать просто profitable SPX options strategy, и ответ - книжки и руководства по опционам продавать!

В учебных целях можно предположить вероятность рецессии 50%.

Annual volatility of returns is one thing. A very specific "known" bimodal distribution is quite another.

you might missed "on average" in the tweet and word "median" on charts.

I get what you meant. My point is that there are no data to support bi-modality in these tweets.
To me, it seems - they took all annual SPX returns >0, took an average and got 15%, and then they took all returns <0, took an average and got -15%. which is totally inline with normal distribution centered at 0.

I can imagine that due to the amount of data - 20 data points of a first rate cut, it could be bi-modal or whatever, but averages (+-15%) don't seem out-of-line from our null hypothesis - the distribution is normal, and "first rate cut" do not have any special meaning.

We can agree to disagree. I think he is communicating exactly this - bimodal. Either there will be a recession, or not.

But I agree that +-15% won't be anything special. This is just an exercise.
