According to HMRC data published in March 2025, high net worth individuals in the top 1% of UK earners bring in at least £201,000 annually before tax. This elite group of approximately 340,000 individuals earns 13.3% of the UK’s total income and pays 28.2% of all income tax collected. Reaching this milestone requires a clear, workable investment strategy, particularly for those looking to transition from high earnings to wealth accumulation.

Beyond real-world investments like private equity, business chains and real estate, many of today’s top earners are building wealth through digital investments. One of the most significant challenges, however, is market volatility, which heavily influences investment decisions, especially for premium portfolios holding large capital.

Understanding Volatility

Volatility is the rate at which the price of an asset rises or falls in a period of time. When an asset’s price fluctuates rapidly between high and low price points, the asset is described as having high volatility. Common assets associated with high volatility include new shares of IPOs, cryptocurrencies like Bitcoin and growth stocks in sectors like technology. The opposite stands true for assets with low volatility such as government bonds and money market instruments such as commercial papers, treasury bills or gilts.

Volatility can also be implied or historical. Implied volatility is the estimated future volatility of an asset, while historical volatility measures how much an asset’s price has actually fluctuated in the past. Both are calculated computationally. However, implied volatility is the industry standard and is published by financial institutions like the London Stock Exchange Group (LSEG) in periodic market reports. Even though volatility is perceived as an indicator for risk, several multi-million-dollar firms rely on the metric for deciding spread betting, algorithmic trading and options trading strategies.

Historically, geopolitical and macroeconomic events have emerged as frequent drivers of large- scale volatility in the global market. While this remains true, another player is leading volatility trends in today’s market.

The new player defining volatility in the global markets

Post COVID-19, the global financial markets have posted increasing volatilities, especially in the wake of new artificial intelligence innovations. The U.S. S&P 500, France’s CAC 40, UK FTSE 100 and other major stock indices have kept an upward trajectory amidst revolutionary AI trends. Artificial intelligence is changing how we work, and for investors, the investments are worth holding for future returns.

But the caveat lies in the fact that, although AI is currently driving new all-time highs in the stock market, it is also exposing portfolios to significant volatility. AI companies falling short of revenue goals and a growing competitive market, leading to concerns about profitability, are part of the trends driving volatility in the global markets.

For example, Deepseek’s release on January 27, 2025, sent the global market panicking after the company declared the AI model could match ChatGPT’s performance. Deepseek launched at a fraction of ChatGPT’s move-to-market; $6 million compared to $100 million plus for OpenAI. Fear that investors may have overinvested in OpenAI, ChatGPT’s creators, sent the tech market crashing. Top institutional investors backing OpenAI, including NVIDIA and Microsoft, crashed 17% and 3%, respectively, in a single day. Other tech stocks like Broadcom and AMD followed, dipping 16% and 6%, respectively.

The new reality is AI has introduced a new edge to the market, and now more than ever, investors need a standard and reliable financial platform like OANDA that provides the execution agility needed to quickly rebalance market exposure as soon as a need arises. How global market volatility shapes premium portfolios Investors view volatility as risk or opportunity, and this influences how they curate investment
portfolios and rebalance them.

1. Promotes dollar-cost averaging (DCA)

Volatility is widely viewed as a risk factor, especially for investment portfolios designed for short-term durations. A highly volatile market means the price of an asset is subject to big price swings, with the possibility of the price not returning to the mean price as quickly if the market loses momentum.

While investors who are looking to invest for a few months may opt for assets less susceptible to volatility. Investors thinking long-term don’t see volatility as a threat, provided the full picture of the price chart points towards profitability. As such, investors adopt dollar cost averaging techniques, purchasing more of an asset at discounted prices during price drops.

2. Inspires investors to choose capital preservation over ROI

High net worth individuals who prioritise capital preservation over jaw-dropping returns mainly opt for assets with low volatility. In this scenario, a wealth management firm can advise portfolio diversification across low-risk, low-volatility assets like government bonds and money market funds. While low-volatility assets may not yield outstanding returns, they do the required job of protecting investors’ capital from the eroding influence of inflation.

3. Makes it difficult to predict the portfolio’s profitability

Many high earners have their net worth tied up in massive, concentrated stock positions. To fund their lifestyles without selling shares and triggering tax events, they leverage these positions to secure Lombard loans. However, on the rare occasion when market volatility tanks the underlying stock, banks issue immediate margin calls. These calls are usually unforgiving, leading to the liquidation of shares at unfavourable prices. Investors end up losing significant portions of their portfolios. As a result, many luxury earners prefer to hold copious amounts of cash while sitting on low-risk equities.

4. Provides ways for investors to exploit changing index correlations

Investors who monitor relationships between global market indices can identify regions or sectors that are outperforming or undervalued during periods of volatility. This enables them to rebalance portfolios strategically. Additionally, investors can set up algorithmic trading or high-frequency trading systems to leverage price volatilities that result from geopolitical events like wars and trade tariffs and macroeconomic shifts such as wars, inflation and interest rate changes.

What This Means for Premium Portfolio Investors

Investors are usually faced with the challenge of interpreting the impact of volatility on premium portfolios. Volatility shapes high-value portfolios starting from asset curation up to strategic next steps laid out for portfolio management or rebalancing during extreme volatility. While some investors are risk-averse, preferring portfolios that have low-volatility. Others embrace high volatility, factoring in the price swings, big or small, that may take place as an asset’s journey to a larger valuation.
