Dow Jones technical error spreads fake news story of Google acquiring Apple

2-3 times year a story like this comes across the news wire and its a good test to see who blindly follows headlines, vs who actually uses the headline and sentiment news as just one of many signals that are mixed together to create a trading signal.

Of course since most algos also have a momentum component, it becomes hard to see who has poor risk management vs who is just following the momentum and piling on:(

I remember two cases, one was about the FED raising rates by 2% and another was that a plane had flown into the whitehouse that was published by the AP.

Rule #1 of machine learning

- No data is clean, no matter how much you pay for the data, there is always noise.

Technical errors don't manufacture false stories from thin air.

Sure, AAPL’s enterprise value is north of $800B, and GOOGL’s market cap is ~$680B. But I bet stranger things have happened in capital markets, albeit not at this scale.

If Alphabet’s board were hell-bent on acquiring Apple, could they get the leverage to do it from anyone short of a national government? (Putting aside the obvious antitrust concerns.)
