Sold at 300. This position lost $700, actually not the first time losing money on UnitedHealth. I think it really proves the saying "The stocks that make you money will always make you money, and the stocks that lose you money will always lose you money." This time I sold not for other reasons, but because I no longer see a bright future for the insurance industry, and the company's fundamentals are starting to deteriorate, which fits my selling logic. Last night, the account was still in the green thanks entirely to $Amazon(AMZN.US). The previous purchase and June calls are already up 60%, and the 2027 calls and sell puts are already up 20% and 30%. Just wait a bit more. $Cleveland Cliffs(CLF.US) has been volatile recently, and the sold calls are already profitable. Just hold until March. Lock in the upside, but can also withstand some downside risk. $Berkshire Hathaway B(BRK.B.US) at this price has already reached the level where Value Brother last added calls, and this time I acted about 1 point too early, bought a June call that's already underwater 10%. No big deal. Finished two books in January: "A Random Walk Down Wall Street" and "Berkshire Hathaway Letters to Shareholders." The goal for February is still to read for 1 hour every day. Only care about the process, the results will follow. Continue sharing "The Most Important Thing in Investing" 1\. You must ensure that when you're engaging in contrarian investing, you not only know that it's opposite to what the crowd is doing, but also where the crowd is wrong. 2\. Contrarian investing is lonely and unsettling. 3\. An investment that "everyone" thinks is great. In my view, by definition, it can't be. 4\. Two essential elements of great investing: Seeing qualities that others don't see or appreciate Turning those qualities into reality 5\. Skepticism is necessary to understand balance sheets deeply, to grasp the latest financial engineering marvels, or those can't-miss stories. ### Related Stocks - [Berkshire Hathaway Inc.
