FYI: While individual securities (such as shares of stock in a publicly traded company or a bond issued by a company or government) do not have an annual expense ratio, mutual funds and ETFs always have an expense ratio. The annual expense ratio of a stock or bond mutual fund directly reduces the return of the investor, which reduces the amount of money that can be safely withdrawn during retirement.

Pfau & Dokken: Why 4% Could Fail - Rethinking Retirement

Wade Pfau’s new book: How Much Can I Spend in Retirement? (@ Bogleheads.org)

Sure, if you trade monthly and one of those funds (that you own for a month) has a high ER, it won't make much of a difference. But if you're flitting from one high cost fund to another, it's no different from owning one high cost fund for the whole year.
Paying 1/12 x 2% for a month, twelve times a year, is the same as owning one 2% fund for the entire year.
I can understand the idea of moving from sector to sector, or region to region, at a frenetic pace. But just as the ER of a single short term holding won't make much difference, ISTM that whoever is managing that single holding also won't make much difference over a very short term.
The other factors that hank mentioned, market trends and asset class valuations strike me as dominant. You can get focused exposure to these factors with low cost ETFs. No need to resort to high priced funds. (Yes, even I will say that ETFs have a role to play. They replace what Fidelity Select Portfolios used to do, back when they traded hourly.)
And of course you can get automatic sector churning, of a sort and so to speak, in the DSE_X funds.
For example, here's E*Trade's footnote (2) on NTF trading there: Of course, these "specially designed funds" come with those high ERs that hank was talking about.
Here's an earlier MFO thread on the same topic:
