Due to the soaring cost of oil in Europe and the United States, prices at gas stations have risen sharply. In particular, the cost of a liter of diesel <a href="https://www.rfi.fr/en/france/20260309-france-launches-nationwide-petrol-station-inspections-as-fuel-prices-jump">has risen</a> by about 16% in France since the last pre-war day on February 27. Psychologist Mikhail Tegin explains why, when the cost of a barrel of Brent oil reaches almost $120, our emotions turn on inside in addition to analysis and calculations: we are ready to sell promising tech sector stocks just because it has become 30% more expensive to fill up the car.

71% of asset management firms plan to <a href="https://www.grantthornton.com/insights/articles/asset-management/2025/ai-is-transforming-asset-management">incorporate</a> generative AI into their operations, according to data from a survey of 500 senior investment industry executives in key global markets conducted by Grant Thornton in partnership with ThoughtLab. Two-thirds say the payoff in AI is still modest, and 12% see no return or negative results. I don't have access to the same resources and infrastructure as BlackRock, for example, or another large money manager. But if the majority is going to implement generative AI, it is logical to ask whether it can already fulfill a basic investment objective at the retail investor level today.

I gave three AI chatbots €500 to invest. Here's what they did with my money

In one week, a new AI tool from Anthropic to automate clerks' work, <a href="https://oninvest.com/article/anthropic-i-openai-vypustili-obnovlenia-v-razgar-rasprodazi-na-rynke-eto-novyj-udar">led to</a> a big sell-off on Wall Street in several industries at once. Investors fear that the new AI capabilities could jeopardize traditional business models. Analysts from New Street Research believe that the fall in markets is due not so much to objective factors as to anxiety. In psychology, particularly cognitive-behavioral psychology, experts describe four rules by which an anxious person lives. In investments, they turn us from analysts into indecisive people or even panickers. Psychologist Mikhail Tegin explains how these mechanisms work on the stock market and how to turn them to your advantage.

Four rules of anxiety: how to stop fearing the AI apocalypse and not expect the worst

Sleep-deprived people <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11611806/">stop perceiving</a> negative feedback, i.e. a losing trade no longer makes the tired person's brain adjust the investment strategy. At the same time, the brain switches to the energy-saving mode and starts using simplified thinking patterns. And although in the world of finance it is commonly believed that success depends on intelligence, in reality this is far from true. Let's see how fatigue not only makes us risky, but also inconsistent in our investments.

The cost of burnout: how sleep deprivation and everyday stress reduce investment returns

The VIX fear index fluctuated in a 19% range this week, first rising to 20.1 points as it approached the edge of the stress zone, and then falling about 16%. Investors were reacting not to objective macroeconomic data but to Donald Trump's plans for Greenland - as a result, U.S. stocks <a href="https://www.ft.com/content/cb1a8211-ac60-4cb2-b68f-955f3d0f98f5">lost</a> more than $1 trillion on Tuesday. In such an environment, reactive decisions can lead to financial losses. Why discipline and system help an investor to act more effectively than intuition and quick analytics - explains psychologist Mikhail Tegin.

$1 trillion loss in a day on fear: How market discipline saves money

Almost everyone has a compelling reason to invest for the long term: to secure a decent retirement, save for their children's education, help them with their first mortgage payment, or simply build up a nest egg for a rainy day. Economist Denis Elakhovsky studied the history of various assets' performance not just over the long term, but over the super-long term, spanning decades and even longer.

200 years of investing: why time helps investors but does not guarantee success


The festive reset easily pushes us toward New Year's resolutions. As we <a href="https://oninvest.com/article/prazdnicnye-obesania-pocemu-oni-bol-se-cem-prosto-spisok-pozelanij">wrote</a> earlier, the plan to become an effective investor and double your income will have to be put into practice at some point.  But almost immediately, our commitments cease to be a source of motivation and begin to weigh on us — every glance at the market or banking app increases our stress. The reason is not weak willpower, but how the brain works and the cognitive traps we create for ourselves.

New Year's resolutions as a cognitive trap: what prevents us from seeing our plans through to the end

The New Year and Christmas often feel like a clean slate, a new phase: an opportunity to reset old habits, "reset" failures and lay the foundation for future success. We make solemn promises to ourselves - commitments: to start running, to read more books or, especially important for investing, to finally strategize and increase our income.

Holiday promises: why they're more than just a wish list

Intuitively, it may seem that for the long-term investor, the best companies are those that consistently make money by selling basic necessities to people, whether the economy is growing or declining. However, a recent<a href="https://www.nber.org/papers/w34402"> article</a> published by the U.S. National Bureau of Economic Research shows that the market is taking a toll on that psychological comfort. Issuers whose businesses are more dependent on the state of the economy have historically generated higher returns than securities of companies with stable earnings.

How crises affect stock returns: cyclical and defensive securities

Have you ever experienced that despite all your knowledge about diversification and long-term planning, you impulsively buy shares of a "hot" company at some point, and then sell them with the same zeal at the first correction? Have you ever wondered why you do this? Or why you avoid the stock market for years, preferring to keep your money only on deposit, although inflation often eats up all the income? The answer to these questions lies not only in the economic news or even in how you interpreted it, but in how you "see" money - in your unconscious beliefs. These are called Money Scripts - Money Scripts. Let's analyze them using the examples of characters from the TV series "Game of Thrones".

Retail investing has undergone a revolution in recent years. Small traders are no longer disorganized individuals, sometimes with a legion of names. Telegram channels with signals, threads on Reddit, profile forums, and "auto follow" functions in brokerage applications have created the illusion that collective intelligence can beat the market.
