Fund Performance: Strong past performance often attracts more investors, increasing demand and thus the price (Net Asset Value). Conversely, poor performance can lead to decreased demand and lower prices.

Market Conditions: Overall market trends, such as bull or bear markets, significantly impact fund prices. Positive market sentiment generally boosts fund values, while negative sentiment can depress them.

Economic Indicators: Economic data releases like inflation rates, GDP growth, and unemployment figures can influence investor confidence and, consequently, fund prices. Strong economic data tends to support higher prices.

Interest Rates: Changes in interest rates can affect the attractiveness of WPOIX.US relative to other investments. Higher interest rates may make fixed-income alternatives more appealing, potentially reducing demand for the fund.

Fund Management: The skill and experience of the fund managers, as well as their investment strategy, play a crucial role. Effective management can lead to better returns and higher fund prices.

Expense Ratio: A lower expense ratio means more of the fund's returns go to investors, making it more attractive. Higher expense ratios can detract from performance and potentially lower prices.

Investor Sentiment: General investor optimism or pessimism about the specific sectors or asset classes held by WPOIX.US can impact demand and price. Fear or greed can drive short-term price fluctuations.
