Could you please clarify for me what you mean by "1 point on SPX"? Are you referring to the Standard & Poor's 500 Index (SPX), and asking how much monetary value is associated with a one-point movement in the index? If so, it's important to note that the value of a single point in the SPX can vary depending on factors such as the overall price level of the index and the composition of its underlying stocks. Generally speaking, however, a one-point move in the SPX can represent a significant amount of money, particularly given the size and liquidity of the index. Could you provide more context or clarify your question further?
