The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

Back in 2017 I had the fortune to buy 1000 shares of NVDA. The price was just over $35. As you may know, it is currently north of $600. There have been a couple of 50% drops along the way, but as I get older I've become more like my late father-in-law who never sold anything.

At any rate, to keep my monkey-mind occupied over the last year I've followed NVDA on a weekly chart with a simple buying approach to at-the-money calls. Whenever NVDA crosses above its 3-week simple moving average I buy ATM calls with six weeks until expiration (NVDA has weekly options). The options are held until the price drops below the SMA or for a max of five weeks.

Since 2014 the strategy has had one losing year. No compounding. Here are the yearly summaries:
      Trades  Ave Return
2014 9 20.7%
2015 12 - 2.8
2016 9 83.8
2017 9 54.8
2018 12 8.2
2019 9 48.5
2020 9 40.7
2021 9 162.8
2022 7 18.4
2023 9 81.9
So, why does this work? First, the overall trend has been up (although with some nasty tumbles). The moving average approach avoids a lot of the downside falls, although one is susceptible to upward blips in a down market.

Second, option returns are asymmetric. You can only lose 100% but can gain more than 100%. The highest return was over 10x.
