#MarketTiming with the NYMO/NYSI and Stocks, ETFs on Today’s buy signal — 1/6/2025

The stock market either goes up or goes down, taking its stocks and ETFs with it. And yet It is amazing how difficult it is to recognize that simplicity.

THE TRADING STRATEGY

Short-term swing trading: When the NYMO turns up, it is time to buy stocks on the next open. When the NYMO turns down it is time to sell stocks on the next open.

Longer-term swing trading: When the NYSI turns up it is time to buy stocks on the next open. When the NYSI turns down, it is time to go to cash or to go short on the next open.

Most stocks and ETFs move with the market.

Simple as that.

01/06/2025 — BEFORE THE OPEN

I’ve been preaching these market-timing tools since I began writing about the stock market, and trading them for now thirty years (oh my god! how time flies!) but once again, to my mind, there is no better market-timing tools than the McClellan Oscillator (the NYMO) and its Summation Index (the NYSI).

Based on NYSE breadth they rotate constantly, like an ever turning wheel, taking stock prices up and down with the direction of each.
