# "Rumor" buy UnitedHealth

I usually scoff at market rumors, because by the time they reach me, I'm most likely the one left holding the bag.

### The only time I received a "reliable" tip, it turned out to be just as unreliable.

  
On March 7 this year, a rumor spread like wildfire in stock circles: "Huawei's Ascend OEM partners are being narrowed down from 13 to five - Superfusion, Huakun Zhenyu, Inspur, Digital China, and Dahua. The rest will transition from OEM to sales agents. This has been cross-verified through multiple channels and can be confirmed with listed companies. Core partners Dahua Technology and Digital China are recommended." I initially dismissed it, but coincidentally, a friend in a senior position at one of these companies (which I won't name) personally confirmed it. Faced with this "reliable" tip (admittedly, I couldn't resist the temptation), I hesitantly bought a small position in XXX that morning. By afternoon, something felt off—the stock price didn't reflect the "valuable" news at all. I sold at the next trading day's open, avoiding a major drop but still losing about 2%. The loss wasn't huge, but this foolish move, which made me want to cry, might as well be a stain on my investment history.

Half a year later, I fell for rumors again and bought shares of $UnitedHealth Group(UNH.US), purchasing a 2.5% position at $306 and placing another 2.5% limit order at $294, aiming to average my cost to $300 (easy to remember 😁, whether it fills is up to fate).

### This time, the referrals were special: one from the "Oracle of Omaha" and another from Duan Yongping. The Oracle bought 5 million shares of $UnitedHealth Group(UNH.US) (worth $1.6 billion) against the trend in Q2, while Duan, after seeing this, said he might follow suit. He humbly admitted he didn't understand insurance, but Buffett did—after all, Berkshire Hathaway has a significant insurance business. In other words, Berkshire already has insurance but still made a big bet on a competitor in Q2, which is worth pondering.

If Duan says he doesn’t understand insurance, I certainly can’t claim to either. Although I made a 50% return on $China Life(02628.HK) this year, I bought it purely for the steep AH discount, thinking its single-digit P/E was dirt cheap.

Those familiar with Buffett know that while Berkshire holds insurers like GEICO, insurance itself contributes little to its earnings. Instead, the industry’s unique float—collecting premiums upfront and paying claims later—lets Buffett earn hefty returns with ultra-low capital costs.

Yet Buffett has repeatedly said insurance isn’t a great investment: it’s hard to differentiate products, competition is fierce, and the "collect now, pay later" model makes it tough to design a foolproof profit formula.

Despite this, Berkshire still bought shares in an insurer it doesn’t even praise. Duan said he’d study insurance, so I’ll lightly follow suit.

Some might ask if this learning cost is unnecessary—why not just observe and buy only after fully understanding? I disagree: you only care if the ship is leaking when you’re on board.

### Here’s my lazy investing tip: follow those who know the industry. If you’re not in it, even thorough research might not match 1/10 of an insider’s knowledge. Duan is shrewd—he knows no one understands insurance better than Buffett and that Buffett’s targets usually yield solid returns. So tailing him on insurance seems like a good bet.
