📊 COSS Markets

COSS Stock Performance Table

Performance analysis courtesy of Shawn Cherian and the OSS Newsletter:

To track the performance of COSS companies, we’ve created an equal-weighted index comprised of public names including: MongoDB, Elastic, Talend, Cloudera, Rapid7, Fastly and Jfrog.

Over the last year, the COSS Index significantly outperformed the benchmarks:

• COSS Index +107%

• NASDAQ +47%

• S&P 500 +23%,q_auto:good,fl_progressive:steep/

Over the last three years, the COSS Index continues to outperform:

• COSS Index +252%

• NASDAQ +81%

• S&P 500 +40%

COSS companies sold off sharply in the last two weeks and while they stayed above their emerging cloud peers, the gap narrowed significantly from a premium of 7.3x multiple turns (two weeks ago) to 1.3x multiple turns today. Of note, all three indices still trade at nearly twice their five-year average reflecting continued strength across the public markets. COSS companies continue to move farther away from both their five-year average as well as their counterpart indexes.

• COSS Index: Current Multiple 15.5x | Five-Year Mean: 6.5x

• Emerging Cloud Index: Current Multiple 14.2x | Five-Year Mean: 8.5x

• NASDAQ Composite: Current Multiple 4.4x | Five-Year Mean: 2.9x
