One in three Sipp holders are buying up shares, while the markets come off last week's highs.
Some pension savers are taking control of their own portfolios and upping their exposure to shares, despite the volatile markets.
Barclays Stockbrokers conducted a poll of its own Self Invested Personal Pension (Sipp) customers for the report, finding that 32 percent were buying shares at the moment. A more conservative nine percent were revealed to be selling shares in the unstable conditions.
The FTSE 100 has registered strong gains over recent weeks, rising well above 4,450 points towards the end of last week from March's low of 3,500. However, the index is now heading back down towards 4,000 once more as the volatility continues.
Barbara-Ann King, head of investments at Barclays Stockbrokers, said: "As volatility continues to dominate financial markets, it is encouraging to see bullish investors take control of their Sipp investments in the search to increase returns.
"It's great to see that the majority of our clients have the confidence to see market volatility as a buying opportunity rather than waiting for a recognised recovery to be established and are investing for their future."
Barclays also revealed that Exchange Traded Funds and Exchange Traded Commodities - a relatively new innovation for investors - were also performing well among Sipp customers, with one in five buying the products.
