Kris Sidial believes most investors get risk wrong. They either don’t hedge tail risk enough, or they pay too much for protection that slowly loses money and becomes frustrating to hold. This leads to “hedge fatigue,” where investors abandon their protection after watching it underperform in calm markets, often right before markets actually crash.

His approach is more practical. Instead of treating tail risk hedging as a constant cost, Kris looks for ways to make it pay for itself. His philosophy aims to keep meaningful downside protection in place while using other strategies to generate returns that help offset its cost.

At Ambrus, the goal is to maintain real tail risk hedge protection for bad market events while using steady, repeatable trading strategies to help cover the cost and manage how that protection is funded and used. For Kris, it’s about staying protected without the hedge constantly draining money in normal markets, so it is still there when it is actually needed during periods of market stress.

Kris Sidial’s journey to becoming Co-CIO of The Ambrus Group is rooted in a clear problem he saw across markets and institutions.

He got into trading through persistence and direct outreach, eventually breaking in after cold-calling a senior trader who gave him his first opportunity in the industry. From there, he built his foundation in volatility trading and learned how markets behave during periods of stress.

He trained under volatility traders focused on equity volatility, tail events, and market anomalies, before working across prop trading, buy-side investing, and an exotics and listed options desk at a large institution. Across these roles, he developed a deep understanding of how risk is priced, and often mispriced, across markets.

This experience led him to a consistent problem he saw in the industry: most tail risk approaches are either ignored or too costly to maintain over time. He co-founded The Ambrus Group to address this gap by building a more sustainable way to maintain tail risk protection while using trading strategies to help offset its cost.

Kris defines tail risk events as rare but severe market moves that can quickly cause large financial losses. While they don’t happen often, he emphasizes that when they do occur, they tend to come as sharp, sudden drops rather than gradual declines. This can include market crashes where indices fall 20% or more in a matter of days, or volatility spikes where prices move violently in both directions as panic sets in and liquidity disappears. 

Kris emphasizes that these events are often intensified by how modern markets are structured. When volatility rises, investors and institutions positioned the wrong way may be forced to adjust quickly, which can accelerate the move even further. In his view, this is why small shocks can quickly turn into much larger market swings. 

For investors, Kris believes the key risk is not day-to-day market movement, but being exposed when these rare events occur. He stresses that understanding these sharp moves, and planning for them in advance is essential for protecting portfolios when markets suddenly shift.

Kris Sidial’s approach to volatility is shaped by experience across prop trading, buy-side investing, and institutional derivatives desks. He focuses on how volatility is priced in real markets, and how that pricing changes when liquidity shifts, positioning gets crowded, or hedging activity increases.

He pays attention to short-term inefficiencies in options markets, where prices can temporarily move away from underlying fundamentals due to supply and demand pressures rather than long-term value.

At Ambrus, this view is applied through strategies that look for mispricing across relative value, dispersion, and volatility dislocations. The goal is to identify where volatility is out of line across different parts of the market and trade that gap. It’s about understanding how volatility behaves in different conditions, and taking advantage when pricing moves out of balance.
