ARK Invest, the New York-based investment management firm led by the popular money manager Cathie Wood, saw its five actively managed exchange-traded funds and two self-indexed ETFs underperform the S&P 500 index in the second quarter.

That said, Ark’s flagship fund $ARK Innovation ETF(ARKK.US)$, which counts electric vehicle maker $Tesla, Inc.(TSLA.US)$ among its top holdings, outperformed the broad-based global indexes. ARKK returned 9.4% in the quarter compared to the S&P 500 Index's return of 8.5%.

For perspective, barring $Roku Inc(ROKU.US)$, which has risen 13% during the second quarter, all the other top four Ark ETF holdings have declined during the period. 

Shares of Tesla, the largest holding for Ark, fell 7.44% in the second quarter, while $Square, INC.(SQ.US)$, $Teladoc Health Inc(TDOC.US)$ and $Spotify Technology SA(SPOT.US)$ fell 2%, 17%, and 9.8%, respectively. 

Here's how each of the ARK ETFs performed in the second quarter:

$ARK Autonomous Technology & Robotics ETF(ARKQ.US)$, which counts Tesla and $JD.com Inc(JD.US)$ among top holdings, underperformed the broad-based market indexes during the quarter led by detractors $Workhorse Group, Inc.(WKHS.US)$ and $Virgin Galactic Holdings Inc(SPCE.US)$.

ARKQ completely shed its positions in both the stocks in the second quarter. 

$3D Systems Corp(DDD.US)$ and $Alphabet Inc-CL C(GOOG.US)$ were among the best performing holdings for ARKQ. 

ARKQ returned 2.7% in the second quarter.

$ARK Next Generation Internet ETF(ARKW.US)$ underperformed the broad-based market indexes during the quarter with a return of 4.5%. $Grayscale Bitcoin Trust(GBTC.US)$ and $Coinbase Global, Inc.(COIN.US)$ were among the top detractors as both suffered from the drop in $Bitcoin(BTC.CC)$ and other cryptocurrencies.

Roku and $The Trade Desk Inc(TTD.US)$ were among the top-performing holdings.

ARKW returned 4.5% in the second quarter.

$ARK Genomic Revolution ETF(ARKG.US)$: Yet another ETF that underperformed the broad-based market indexes during the quarter. Both Teladoc and $Iovance Biotherapeutics Inc(IOVA.US)$ were among the top losers.

TDOC depreciated amid competitive incursions into the digital health space including that of $Amazon.Com Inc(AMZN.US)$. Iovance disclosed that Maria Fardis, CEO for the last five years, would be leaving to pursue other opportunities. 

ARKG surged 4.25% in the second quarter.

$ARK Fintech Innovation ETF(ARKF.US)$ too underperformed the broad-based market indexes during the quarter led by $Silvergate Capital Corp(SI.US)$ and Coinbase. Silvergate Capital shares traded down, primarily in response to a sharp drop in the prices of cryptocurrencies.

$Shopify Inc(SHOP.US)$ was among the top performers.

ARKF returned 5.9% in the second quarter.

$ARK Space Exploration & Innovation ETF(ARKX.US)$ underperformed the broad-based market indexes during the quarter led by $KOMATSU(KMTUY.US)$, which suffered from a broader selloff in construction and mining stocks and SPCE.

$NVIDIA Corp(NVDA.US)$ was among the top contributors and appreciated in response to stronger than expected first-quarter earnings and guidance, a higher probability that it will succeed in acquiring ARM, sell-side upgrades, and a strong move in semiconductor stocks.

ARKX, the newest ETF which completed a quarter in June since it began trading, returned 2.14% in the second quarter.
