$Apple (AAPL.US)$ In 2017, I briefly held shares for half a year. In 2018, I re-entered the market and persisted for two years. At the beginning of 2020, I was shaken out by a wave of pandemic. Value investing through cycles is really difficult, only realizing how many opportunities have been missed in hindsight. Fortunately, the money from these years of mobile phones has all been earned back.
