I’ve received a lot of comments from people who believe today’s market is fundamentally different, that O’Neil did not trade stocks with this level of volatility, and that past leaders did not have comparable price swings, ADRs, or ATRs.
Qualcomm in 1999 directly challenges that assumption.
O’Neil absolutely traded highly volatile stocks during highly volatile market periods. The names, industries, and technology may change, but powerful leaders with wide price swings are NOT new.
I added an important Qualcomm 1999 example to this post that I left out when I originally published it.
When I recreated O’Neil’s Qualcomm setup using historical data, I found that a stop below the most recent higher low would have been about 10.1%, outside his traditional 7% to 8% guideline.
But a stop at the low of the high-volume breakout day would have been roughly 6.2%, keeping the trade comfortably within O’Neil’s framework.
Qualcomm was highly volatile and still went on to produce an extraordinary advance. It is a strong reminder that fast-moving market leaders are not unique to today’s market.
The lesson is not that O’Neil ignored his rule. We do not know the exact stop he used. The lesson is that a more precise entry and stop location can sometimes allow you to participate in a volatile leader without accepting a wider stop loss.
I added all three Qualcomm charts and the full breakdown to the article. Take another look at the updated post.
