Summit Partners Portfolio Concentration: Heavy Exposure in Tech and Healthcare Stocks

Summit Partners L P's portfolio, valued at approximately $49.1 million as of September 30, 2026, demonstrates a notable concentration in specific sectors and individual holdings. The fund's holdings are dominated by Technology and Healthcare stocks, accounting for the vast majority of its assets, with these two sectors representing 45.84% and 40.74% of the total portfolio value respectively. This indicates a significant tilt towards these two sectors, suggesting that the fund manager likely has a strategic focus or conviction in these areas.

Within the Technology sector, KLaviyo Inc. (KVYO) stands out as the largest position, representing a substantial 44.39% allocation. KVYO, a leading customer data platform company, has seen a significant reduction in its holding, with a decrease of 26.52% in shares and a corresponding value reduction of $5 million, bringing its position down to $217.9 million. This reduction, however, still leaves KVYO as a dominant position within the fund's portfolio. For more details on KLaviyo Inc., you can visit their profile at InsiderSet.

The remaining portfolio is allocated to other sectors and smaller positions. The Consumer Cyclical sector holds a significant portion of the portfolio, specifically A K A Brands Holding Corp. (AKA), which accounts for 13.42% of the portfolio value ($65.86 million). This position remained unchanged in terms of share count from the previous period. Other Technology holdings include A10 Networks Inc. (ATEN) and MACOM Tech Solutions Holdings Inc. (MTSI), though they represent much smaller allocations of 1.1% and 0.35% respectively. A10 Networks (ATEN) maintains a stable position, while MACOM Tech Solutions Holdings (MTSI) is a very minor holding. Details on A K A Brands can be found at InsiderSet.

Summit Partners' portfolio is characterized by its significant concentration in just two sectors: Technology and Healthcare, which together make up 86.58% of the total portfolio value. This level of sector concentration can indicate a targeted investment approach focused on innovation and growth in these areas. The fund holds five distinct positions, but the top two holdings, KVYO and LFST, alone constitute a large portion of the portfolio, highlighting a significant concentration in these specific companies. The reductions in KVYO and LFST suggest that the fund manager might be rebalancing the portfolio or reassessing these positions, but the core concentration remains high.

The fund's holdings reflect a strong preference for Technology and Healthcare stocks, with KVYO and LFST leading the way. KVYO's 44.39% allocation makes it the single largest holding, while LFST's 40.74% allocation is the second largest. AKA is the third largest holding, representing the Consumer Cyclical sector. The stable positions in ATEN and MTSI indicate some diversification within the Technology sector, albeit minor.

Overall, the portfolio's structure points to a focused investment strategy with high exposure to specific sectors and individual stocks. While the fund holds five companies, the top two alone represent nearly 85% of the portfolio. The recent reductions in KVYO and LFST might be part of normal portfolio management activities, but they do not diminish the overall concentration in these sectors. Investors analyzing Summit Partners should be aware of this significant weighting towards Technology and Healthcare, particularly in the large positions held in KLaviyo and Lifewestech Group.
