The AI vs. Human Investor Showdown: ChatGPT's Market Ride into Week 2

The world of finance is constantly seeking an edge, and in an era dominated by artificial intelligence, the question naturally arises: Can AI truly outperform the seasoned human investor? We’re now two weeks into our fascinating experiment, pitting ChatGPT’s stock selections against the tried-and-true performance of a traditional FTSE 100 tracker fund.

And if Week 1 was a testament to AI’s potential, Week 2 delivered a dose of market reality, creating a captivating twist in our ongoing financial saga.

When we last checked in, ChatGPT had made a spectacular debut, its meticulously chosen portfolio of five stocks – JD Sports, Scottish Mortgage Investment Trust, Ocado, Rolls-Royce, and Games Workshop – having soared by a remarkable £427.60.

In stark contrast, the FTSE 100 fund, while respectable, had only managed a modest gain of £130.40. The AI was not just leading; it was leaving its human-backed counterpart in the dust, prompting murmurs of a new era in algorithmic investing.

However, the stock market is a fickle beast, and Week 2 proved to be a humbling experience for our digital oracle.

As the trading week concluded, ChatGPT’s portfolio experienced its first significant stumble. The value of its holdings, which began the week at £1,053.40, dipped by a noticeable £193.20, closing at £860.20. It was a sharp correction, reminding us that even the smartest algorithms are not immune to market volatility and the inherent risks of stock picking.

Meanwhile, the traditional FTSE 100 fund quietly continued its upward trajectory.

Starting the week at £1,013.04, it added another £101.40 to its value, ending at a comfortable £1,114.44. This shift meant that for the first time in our experiment, the traditional fund had significantly outperformed ChatGPT’s portfolio within a single week.

Let's delve deeper into ChatGPT's individual stock performance during this challenging week.

JD Sports, a strong performer in Week 1, saw its value drop from £128.30 to £114.70. Scottish Mortgage Investment Trust, another initial success story, also pulled back from £189.20 to £168.00. Ocado, which had previously seen a decent rise, dipped from £145.40 to £127.80. Rolls-Royce, while not experiencing as steep a decline as others, still saw its value slide from £161.70 to £157.80.

Games Workshop, initially a standout, also faced a downturn, moving from £428.80 to £291.90.

Despite this weekly setback, it's crucial to look at the bigger picture. When we consider the cumulative performance since the experiment began, ChatGPT's portfolio, despite its Week 2 dip, still maintains a lead over the FTSE 100 fund.

The AI-selected stocks started at an initial investment of £1,000 and, even after the recent decline, are still showing a total gain of £234.40 over the two weeks. The FTSE 100 fund, starting from the same £1,000, has accumulated a total gain of £231.80.

This puts ChatGPT just narrowly ahead, a testament to its explosive start.

The gap has significantly narrowed, transforming what once seemed like an AI runaway victory into a neck-and-neck race. The experiment truly highlights the unpredictable nature of the stock market and the delicate balance between high-risk, high-reward individual stock picking and the steadier, diversified approach of an index fund.

As we move into Week 3, the stakes are higher than ever.

Can ChatGPT recover its momentum and widen the gap once more? Or will the consistent, less volatile growth of the traditional fund ultimately prove to be the superior long-term strategy? This evolving narrative promises to offer invaluable insights into the capabilities and limitations of AI in the complex world of financial investment.
