Trading Takes Its TollOne of the points I have made in previous discussions of the merits of round-the-clock trading in this column is that the impact on traders must be taken into account.A recent study looked at the factors that contribute to stress and found that career uncertainty, mounting compliance demands and the quest for work-life balance pale in comparison to the primary source of angst for buy-side equity traders: technology.Singapore Summit: Meet the largest APAC brokers you know (and those you still don't!)Just over half (51%) of the traders surveyed cited internal technology issues as their single biggest source of fatigue or burnout.Jesse Forster, senior analyst in market structure & technology at Crisil's Coalition Greenwich and the author of the study, noted that the rapid growth of electronic trading has reduced patience for IT failure.“Traders see volatility, long hours and performance pressure as part of the job,” he says. “But with e-trading increasing expectations for speed and scale, traders increasingly view problems with technology tools as completely unacceptable.”Modern electronic workflows amplify small failures into a constant drag that one trader referred to as ‘death by a thousand cuts’. Relatively small but ongoing technology issues persist on trading desks because they are not serious enough to warrant attention over other IT priorities, meaning traders are forced to tolerate the status quo.Survey respondents described persistent issues including login delays, inconsistent data across platforms, lagging analytics and unreliable execution tools.Forster observes that although individually these issues are not catastrophic, collectively they drain energy over the course of a day – especially when traders see these issues as fixable.Traders are judged on execution quality, including price, timing, slippage and market impact. When they feel they cannot control the systems driving those results, it will inevitably escalate from frustration to longer-term anxiety, avoidance and fear of misattribution.Technology issues uniquely create both productivity loss and burnout via rising cognitive load, according to Forster. “Instead of trusting systems, traders must verify them, remember workarounds, track exceptions and double-check fields, feeds and configurations,” he says. “This consumes mental energy and leaves less capacity for execution and alpha generation.”Variations on a ThemeTraders love an acronym. From ATH (all-time high) to SL/TP (stop loss/take profit), via EMA (exponential moving average) and FOK (fill or kill), it can sometimes feel like they are speaking a different language.One of the acronyms currently in use is HALO, or heavy assets, low obsolescence companies – an investment strategy that emphasises firms with substantial physical infrastructure, strong barriers to entry and lasting economic significance, which are often viewed as less exposed to AI disruption.Read more: eToro Launches Long-Term Thematic Portfolio Using Amundi ETFs for Retail InvestorsIllustrative examples include utilities, transportation infrastructure and industrial machinery.An investor survey conducted in mid-2025 by ETF data platform Trackinsight found that more than half of respondents intended to broaden their thematic exposure over the following six months.However, physical assets do not always deliver. HALO-themed ETFs have been introduced rapidly and with strong promotion, sometimes based on little more than a bank research note, only to fall flat.Simonelle Mody, associate investment specialist at Morningstar Australia, refers to the volatility of thematic funds and notes that fear of missing out attracts investors who chase short-term returns, despite research showing these funds rarely achieve a desirable outcome.Capital cycle and crowding update for thematic ETF's.

Mody suggests that thematic fund survival and success rates, compared to global equities, make it hard to justify choosing a thematic fund over a broadly based ETF.Capital Group Canada’s senior product specialist, Warner Wen, also questions the long-term value of thematic ETFs when it comes to wealth creation, noting that market data suggests the odds are against investors who try to pick a thematic fund that performs well.This underperformance reflects the challenges these strategies face, particularly in volatile or shifting market environments where diversification tends to outperform concentrated thematic bets.According to Wen, many thematic funds are launched at the peak of hype cycles, only to falter as interest falls or the underlying companies fail to deliver.Bloomberg Not in Terminal DeclineMark Twain’s comment upon hearing reports of his death has been used to describe many events that were widely reported but had not actually happened. More recently, it has been applied to the subscription-based software system that traders have been using for real-time market data, analytics, news and secure trading since the early 1980s.The Bloomberg terminal’s dominance of the financial data market has caused much angst over the years and has clear cult-like undertones. Some users refer to their terminals by name, while others describe them as the most important relationship in their lives (let’s hope their spouses have a sense of humour).The founder of Bloomberg Terminal explaining the function that makes the $24,000 worth it.I wrote about this exact function in the Article below. Must Read, no matter what. https://t.co/aymzqNwuo2 pic.twitter.com/XIQN1S46Rf— Roan (@RohOnChain) April 2, 2026Unsurprisingly, proponents of AI have been trying to replicate it at a much lower cost than the $24,000+ annual subscription. However, the reaction to a recent Wall Street Journal article looking at “alternatives” such as Perplexity underlined how difficult it is to reproduce this software at a lower cost.One observation was that the core value of Bloomberg terminals lies not only in the information itself but also in the long-term accumulation of high-quality data, user habits and industry network effects, making them difficult to replace in the short term. However, there was also an acknowledgement that AI is lowering the barriers to information access and analysis, which may gradually reduce its premium pricing power.Another point was that while it is easy to assume data and speed are everything, in finance, access to a trusted network of professionals still carries significant value and shows that even advanced AI tools cannot easily replicate community and trust built over decades.Perhaps the most relevant observation was that there is a big difference between a helpful AI tool and replacing decades of infrastructure, proprietary data and workflows, and that although tools like Claude or ChatGPT can speed up analysis, modelling and research, they are complements rather than substitutes.This article was written by Paul Golden at www.financemagnates.com.
