When can you interpret a pre-post difference as causal? Let's walk through an example using the case of the Chicago Bears and visiting London. First, review the data: 1. Caleb's development looks great. All is going well. Consistent and impressive improvement week-to-week. 2. The Bears go to London. 3. The Bears haven't scored a touchdown in two weeks and only score 3 points against the 2-7 Patriots. Next, immediately panic and come to the only plausible conclusion: it is the city of London's fault that Caleb Williams is no longer just throwing quick, open check-downs. That is how you use pre-post differences responsibly.

Today, the world mourns the loss of a legend: Jim Simons, an extraordinary investor and mathematical genius, has passed away. Simons founded Renaissance Technologies, a groundbreaking investment firm that achieved remarkable success. His innovative quantitative hedge fund delivered staggering returns, averaging over 66% annually before fees and 39% after fees from 1988 to 2018. To illustrate his incredible impact, consider this: if you had invested $10,000 in Simons' Medallion Fund in 1988, your investment would now be worth $420 million. In comparison, that same $10,000 investment in the S&P 500 would amount to $400,000, while investing in Warren Buffett's Berkshire Hathaway would yield $1.5 million. Simons' legacy extends beyond his financial achievements. He famously remarked, "I did a lot of math. I made a lot of money, and I gave almost all of it away. That's the story of my life." His philanthropy, coupled with his unparalleled success, solidifies his status as a true pioneer in the world of investing. Today, we bid farewell to a quant king whose contributions forever changed the game of investing. Jim Simons will be remembered as a legend. #JimSimons #QuantitativeInvesting #TheWallStreetJournal

This chart is demolishing for the journalism industry. And by the way, it also shows that the decline was already underway before social media were born so don't blame (just) social media, there is something else that could be done better. We know that data are a bit better for media in Europe... but the general trend reamins.

🔮 Once upon a time in the whimsical world of financial fairgrounds, the conservatives found themselves riding a rollicking carousel, spinning uncontrollably thanks to the Banks' unexpected maintenance check. The President, donning his best showman hat, waltzed up, megaphone in hand, declaring, Let there be balance! 🎭 The banks, much like cagey fortune tellers, murmured their reluctant compliance, promising not to yank the rug out from under any political persuasion at their bidding booths. But like overly cautious tightrope walkers, they warily eyed the ground below. 🔍 Here's our crystal ball gaze into the circus: - 🎟️ Ringmaster Resolution: Will this puff of confetti actually restore peace in the tent or just send more gumdrops into the popcorn machine? Call me skeptical — these rides have a knack for going off-script. - 🎡 Carnival of Contrasts: An amusing paradox emerges — those who cry 'free market!’ often become maestros of government intervention when their barker's best interest clashes with their principles. - 🎠 Future Forecast: Expect the merry-go-round to keep spinning, a centrifugal force drawing unusual alliances, while coin-tossing games persistently capture the attention of curious onlookers. 💫 Meanwhile, let’s stop and ponder a world where lending clowns juggle political preferences with customer accounts. The thought is as elusive as walking a tightrope blindfolded — possible, yet nerve-wracking at best. ➖ And so, as the financial fairground draws to dusk, where elephants tiptoe and lions whisper show-ending secrets, it’s with bated breath we await the circus’ next dazzling act. 💡 Remember, life is a tightrope between economics and ethics — sometimes we sway, yet sometimes it’s the sway that steadies the path. https://lnkd.in/emdgfXDV #FinancialCircus #BanksAndBalance #PoliticalEconomy #EconomicEthics #ShowtimeInFinance #TightropeEconomy #LifeIsACircus
