Fund performance: Strong past performance usually attracts more investors, increasing demand and potentially the price. Conversely, poor performance can lead to outflows and a price decrease.

Interest rates: Rising interest rates can make bond funds like JHLVX less attractive, decreasing their price. Falling rates can have the opposite effect.

Credit risk: Changes in the perceived creditworthiness of the bonds held by JHLVX will impact its price. Downgrades can lower the price, while upgrades can increase it.

Market sentiment: Overall investor confidence and risk appetite can affect demand for JHLVX. During risk-off periods, investors may sell bonds, impacting the fund's price.

Fund size/flows: Large inflows can sometimes pressure fund managers to deploy capital quickly, potentially affecting returns. Outflows may force them to sell holdings, influencing the price.

Expense ratio: Although not a direct price determinant, a higher expense ratio can detract from net returns, making JHLVX less attractive compared to similar funds with lower fees.
